This International Standard deals with the safety of hand-held motor-operated or magnetically driven electric tools, the rated voltage of the tools being not more than 250 V for single-phase a.c. or d.c. tools, and 440 V for three-phase a.c. tools.So far as is practicable, this standard deals with the common hazards presented by hand-heldtools, which are encountered by all persons in the common use of the tools.Tools with an electric heating element are within the scope of this standard. They should alsocomply with relevant parts of IEC 60335.Hand-held electric tools, hereinafter referred to as tools, which can be mounted on a supportfor use as fixed tools without any alteration of the tool itself, are within the scope of this standard. Unless the requirement for such support is given in a relevant part 2, this standard alone will not be sufficient to ensure that the combination of tool and support is adequate.Requirements for motors not isolated from the supply, and having basic insulation not designed for the rated voltage of the tools, are given in Annex B.
